A method for the synthesis of bicyclic N-heterocyclic cores from N-terminal α,β-unsaturated diazoketones has been developed. The transformation involves three sequential steps that include N-deprotection, an intramolecular aza-Michael, and a photochemical Wolff rearrangement as a one-pot protocol. By using this strategy, a series of substituted bicyclic N-heterocycles, particularly, indolizidines and pyrrolizidines, were synthesize in good yields.

The site-selective functionalization of unactivated aliphatic amines is an attractive and challenging synthetic approach. We herein report a general strategy for the remote site-selective functionalization of unactivated C(sp3)-H bonds in amides by photogenerated amidyl radicals to form gem-difluoroalkenes with trifluoromethyl-substituted alkenes. The site selectivity is controlled by a 1,5-hydrogen atom transfer (HAT) process of the amide. This photocatalyzed transformation shows both chemo- and site-selectivity, facilitating the formation of a secondary, tertiary, or quaternary carbon center.
